As the light envelopes us I feel very different Jenny doesn't wear a bra often so I feel my small breasts rubbing against my tee shirt and my pants feel overly tight. My underware feels like a wedgie as it rides up between my overly plump ass checks. My periforials as blocked by cascading red hair and I realize quickly I have been swapped into Jenny's body and before I can even scream another flash happens. This time I feel a pressure growing in my chest as I swapped sizes with an overweight lady Infront of us. I can't help my whimper as my once small tits swell into massive proportions quickly passing anything reasonable for a girl my size. I don't know how big they are but they have unzipped my jacket to make enough room and they are jiggling out of control. My new nipples have to be 6in across and pocking out as every breath I take caused a new ripple. Jenny isn't doing much better as she grows 5in in height and packs on 60lbs of rock hard muscle. My clothing she had on is stressed to the max and even my old shoes ripped apart as her feet grew.
